SKL 853 7
2.8 Travel operation Before putting the earth-moving machine into operation, the driver’s seat, mirrors and controls must be adjusted so as to ensure safe working.
The windows must be clean and free of ice.
Driving tracks must be designed so as to ensure smooth, safe operation, i.e. they must be sufficiently wide, on ground which has as few slopes as possible and sufficient carrying capacity.
Downhill tracks must be set out in such a way that earth-moving machines can be safely braked.
Before driving downhill, the appropriate gear for the terrain must be selected and the gear lever must not be moved during downhill travel (normal or crawler gear).
On steep drops and uphill gradients, the load must be carried on the uphill side, if possible, in order to increase stability.
The carrying capacity of bridges, cellar roofs, vaults, etc. must be verified before the earth-moving machine can drive over them.
The internal dimensions of constructions must be noted before entering underground passages, tunnels, etc.
Earth-moving machines may only be driven on the open road when the machine and the driver both have the appropriate licence as required by the national traffic laws of the country in question. According to the Regulations Authorizing the Use of Vehicles for Road Traffic (StVZO) in Germany, the following equipment must be kept with the machine and provided by the plant operator: • warning triangle • hazard lights • first-aid box
Outside areas covered by general traffic regulations, e.g. on construction sites, traffic regulations should be applied in the proper manner. This should also apply with regard to drivers’ licences. 2.9 Operation Daily before commencing work and after every change of work attachments, the machine operator must check the correct fastening of the work attachments as well as the correct locking of the quick-mount hitch. Work attachments are to be carefully moved at low height. During this check no one must be in the danger zone of earth-moving machines.
The machine operator may only swing the work equipment over occupied driver’s seats, operator consoles and workplaces of other machines when these are protected by overhead guards (FOPS).
If a cab does not have the required protection, the driver of this vehicle must leave the operator’s stand when the work equipment has to be slewed overhead.
The vehicles must be loaded in such a manner as to ensure that there is no overloading and no material can be lost during travel. The vehicle must be loaded from the lowest possible height.
At dumping points, earth-moving machines may only be operated when suitable measures have been taken to prevent rolling or falling. 2.10 Guides
SKL 853 8
Guides must be easily recognizable, e.g. by means of warning clothing. They must remain within the machine operator’s field of vision.
While guiding the machine, guides must not be given other jobs which may distract them from their task. 2.11 Danger of falling objects Earth-moving machines may only be used where there is a danger of falling objects when the operator’s stand has an overhead guard (FOPS). A front guard must be employed if there is a risk of materials breaking into the cab.
In front of walls e.g. of stacked materials, earth-moving machines must be positioned and operated in such a way that the driver’s seat and entry to the driver’s seat are not situated on the side facing the wall.
Demolition work may only be performed by earth-moving machines where there is no danger to persons. See regulations book „Demolition work“ (ZH 1/614) published by the Tiefbau-Berufsgenossenschaft (the employer’s liability insurance association). 2.12 Working in the vicinity of underground power lines Before commencing excavating work using earth-moving machines, it must be determined whether any underground power lines are present in the intended working zone which may present a danger to persons. If underground power lines are present, their exact position and course must be determined in consultation with the proprietor or operator of the lines, and the necessary safety precautions decided and implemented. The course of power lines in the work area must be clearly marked, under supervision, before commencing any excavation work. If the position of lines cannot be determined,
search ditches must be dug - manually, if need be. If underground power lines are encountered unexpectedly or they or their protective covers are damaged, the machine operator must discontinue work immediately and notify the supervisor.
SKL 853 9
2.13 Working in the vicinity of overhead power lines When the earth-moving machine is being used in the vicinity of overhead power lines and trolley wires, a safety distance which varies depending upon the nominal voltage of the overhead line must be maintained between the lines and the earth-moving machine and its work equipment, in order to prevent current overspill. This also applies to the distance between these lines and attached implements or loads.
The safety distances specified below must be complied with:
Nominal voltage in
Volt Safety distance in
metres - 1000 V 1.0 m
over 1 kV - 110 kV 3.0 m over 110 kV - 220 kV 4.0 m over 220 kV - 380 kV 5.0 m
nom. voltage unknown
5.0 m
In the observation of safety distances, all working movements of earth-moving machines, e.g. positions of the work equipment and the dimensions of attached loads must be taken into consideration. Uneven ground which would cause the earth-moving machine to be inclined and thus nearer to overhead lines must also be taken into account.
During work in windy conditions, both overhead lines and work equipment may swing out, thus reducing the safety distance.
If it is impossible to maintain sufficient distance from overhead power lines and trolley wires, the plant operator must consult with the proprietor or operator of the overhead lines to find other safety precautions to prevent current overspill. Such measures could be, e.g.
• Switching off the current • Re-routing the overhead line • Cabling, or • Limiting the work zone of earth-moving
machines.
2.14 Operation in closed rooms If earth-moving machines are used in closed rooms, these areas must be sufficiently ventilated and the special regulations observed. 2.15 Work stoppages Before rest periods and at the end of the working day, the driver of the earth-moving machine must park the latter on ground which has sufficient carrying capacity and is as even as possible, and must secure it against unintended movement.
Before rest periods and at the end of the working day, the driver must lower the work equipment onto the ground or secure it so that it cannot move about.
The driver may not leave the earth-moving machine when the work equipment has not been lowered to the ground or secured.
Earth-moving machines may only be parked in places where they do not present an obstacle, e.g. on the construction site or to plant traffic. Warning devices, e.g. triangles, warning cordons, flashing or hazard lights are to be used if necessary.
Before leaving the operator stand, the driver must bring all operating equipment into home position, switch off the working hydraulics and apply the brakes.
If the driver is leaving the earth-moving machine unattended, he must first turn off the drive motors and ensure that they cannot be started up by unauthorized persons (e.g. removing ignition keys).
2.16 Change of work attachments, maintenance, repair
SKL 853 10
Earth-moving machines may only be converted, maintained or serviced under the guidance of a suitable person designated by the plant operator and following the manufacturer’s operating instructions.
After every change of work attachments, the driver must convince himself that the quick-mount hitch is correctly fastened and locked.
Work on e.g. • braking, • steering, • hydraulic and • electric systems of the machine may only be carried out by expert personnel specially trained in these areas. Stability must be ensured during all type of work on the machine at all times. The work equipment must be secured against movement by lowering it to the ground or equivalent measures, e.g. cylinder supports, trestles. With the engine running, the unprotected articulation range of articulated loaders must not be entered. When jacking up earth-moving machines, jacking devices must be positioned so that they cannot slip. Jacks must be positioned and applied absolutely straight, without tilting. Raised earth-moving machines must be supported by suitable structures such as crosswise stacks of planks, square timbers or steel trusses. Earth-moving machines which are raised with work equipment must be stabilized by a supporting structure immediately after lifting. Work under machines which are only supported by their hydraulics is forbidden.
The engine/motor must be turned off prior to all maintenance and repair work. These requirements may only be ignored in the case of maintenance or repair work which cannot be performed without the engine/motor running.
When performing maintenance and repair work on the hydraulic system, the latter must be relieved of pressure. With the engine
turned off, lower the work equipment to the ground and actuate all hydraulic control levers until there is no pressure in the hydraulic system. Before working on the electrics or when performing arc-welding on the machine, the connection to the battery must be interrupted. When disconnecting the battery, first the negative pole then the positive pole must be disconnected. The battery must be re-connected in reverse order.
During repair work around the battery, the latter must be covered with insulating material; tools must not be deposited on the battery.
Protective devices of moving machine parts may only be opened or removed when the drive has been switched off and cannot be switched on again by unauthorized persons.
Protective devices are e.g. engine/motor covers, doors, protective grating, trim. Upon completion of assembly, maintenance or repair work, all protective devices must once more be attached in the proper manner.
Load-bearing parts of earth-moving machines may only be welded following consultation with the manufacturer and in accordance with recognized welding principles.
Overhead guards (FOPS) must not be welded or drilled in any way which could impair their sturdiness. Alterations, such as welding of the hydraulic system, may only be undertaken with the manufacturer’s permission.
Before commencing work on the hydraulic system, the operating pressure, pilot pressure, back pressure and pressure inside the tank must be let off.
SKL 853 11
Swallowing lubricants, or long and repeated skin contact, can be hazardous to health. When used properly, there is no particular danger to health. The safety specification sheets from the mineral companies must be observed. Only the hoses specified by the manufacturer may be used. Hydraulic hoses must be routed and assembled by expert personnel. In the vicinity of fuel or batteries, smoking and naked flames are prohibited. 2.17 Recovery, loading, transportation Earth-moving machines may only be loaded onto recovery vehicles when adequate towing vehicles are used.
The tow fixing points specified by the manufacturer must be employed.
For loading and transportation, earth-moving machines and all necessary auxiliary equipment must be secured against unwanted movement.
The travelling gear and track-laying gear of earth-moving machines must be sufficiently cleaned of mud, snow and ice to ensure that ramps can be driven up without risk of slipping.
When transporting the earth-moving machine on trucks, flatbed trailers, or by rail, it must be sufficiently secured with chocks and by attachment to the lashing points.
Before setting off, the route to be taken must be examined to determine whether the roads are wide enough, entrances and passages under bridges are large enough and that roads and bridges have sufficient carrying capacity.
2.18 Monitoring and inspections
The machine must be submitted to a general inspection according to the existing UVV-regulations (Accident Prevention Regulations). This inspection must be carried out by an expert (e.g. machine engineer or machine foreman): • before the machine is put into operation for
the first time and before the machine is again put into operation when essential modifications have been made
• at least once a year • in the meantime, according to operating
conditions and local environments The results of this inspection have to be recorded in writing and this record has to be kept until the next inspection takes place.
Prior to every work shift, the machine operator must check the earth-moving machine according to inspection plan.
Hydraulic hoses must be replaced as soon as the following damages are recognized:
• Damages to the outer layer which reach the intermediate layer
• Embrittled patches on the outer layer • Deformations when under pressure or
without pressure which differ from the original shape of the installed hose

4.8 Driving, steering and braking 4.8.1 Driving
Note When driving on public roads, the wheel loader, as a self-propelled work machine, is subject to legal regulations (in the Federal Republic of Germany, the StVZO and StVO).
Attention The vehicle has a direction-of-travel-selection switch on the instrument panel and another such switch on the actuating lever for the working hydraulics. When driving on roads the direction-of-travel-selection switch (10/46) on the instrument panel is active due to the deactivation of the actuating lever via the multi-function switch (10/35). Before operating the actuating lever care must be taken to ensure that both direction-of-travel-selection switches are set in the same direction. The multi-function switch can only be pressed when the machine is at a standstill in order to avoid unintentional braking or changes in the travel direction.
Fig. 10-Actuation
SKL 853 33
Driving off • Direction-of-travel selector rocker switch in
joystick (10/7) and on instrument panel (10/46) set to “O”- neutral.
• Start engine. • Raise lift frame up to the “Drive” height
mark (12/1). • Select gear range “I” or “II” only in high-
speed version (10/34).
Note Pay attention to indicator lamp!
• Select travel range “fast” or “slow” (10/33) as required.
• Release parking brake (10/5). • Set the desired travel direction with the
direction-of-travel selector (10/7 and 10/46).
• Press the accelerator pedal (10/4). The automatic clutch means that the machine only drives off once a certain engine speed is reached.
• The driving speed is regulated by means of the accelerator pedal. Driving speed is directly dependent upon engine speed.
• The direction of travel may be changed quickly by means of the selector lever.
Coming to a halt • The travel speed is reduced by releasing
the accelerator pedal. The hydrostatic drive then acts as a non-wearing auxiliary brake.
• See also section 4.8.3, “brakes”.

7 Care and maintenance 7.1 General notes The good operating condition and life expectancy of machines are largely influenced by care and maintenance. For this reason, it is in every machine owner’s interest to perform the specified maintenance work and comply with the service intervals. This section deals in detail with periodic maintenance, inspection and lubricating tasks. Furthermore, during the warranty period three thorough inspections are stipulated, which must be carried out by trained specialist personnel. Type-specific maintenance and inspection plans for this purpose are contained in every instruction book and every warranty certificate.
Inspection intervals
1st inspection after approx. 100 operating hours 2nd inspection after approx. 500 operating hours 3rd inspection after approx. 1000 operating hours Subsequently, every 500 operating hours
Note The three inspections are obligatory and must be paid for. If they are omitted, the warranty may be subject to restrictions.

Note Service parts for inspections should be ordered well in advance!
Lubricants • The machine’s life expectancy and operating condition are largely dependent upon the use of
the specified lubricants and compliance with the service intervals. • If lubricants which do not conform to our recommendations are used, consequential damages
may occur for which we will not assume liability, even inside the warranty period. • For lubricant specifications see section 3.9.
46 5.97 SKL 853
7.3 Care and cleaning
Note The machine must be cleaned on a suitable surface with an oil separator.
• Neither a steam-jet appliance nor a high-
pressure cleaning apparatus may be used for cleaning during the first two months after the machine is used for the first time or when newly painted to avoid damage to the paint.
• Do not use aggressive detergents for
cleaning the machine. We recommend using commercially available cleaning agents for passenger cars.
• When cleaning with a steam-jet appliance,
the hot water jet must not exceed 80 °C and a spray pressure of 20 bar. The nozzle must be at a minimum distance of 30 cm from the machine.
• Linings (insulating materials, etc.) must not
be exposed directly to water, steam or high-pressure jets.
• When cleaning with water or steam jets,
take care not to spray exhaust-gas and air filter openings.
• If cleaning the engine with water or steam
jets, do not expose sensitive engine parts, such as generator, cabling, oil pressure switch, etc. directly to the jet.
• After each wet clean, the machine must be
lubricated in accordance with the lubricating plan and a test of all work cycles, steering and driving functions carried out.
7.4 Notes for winter operation
The following points - and the relevant notes in the engine instruction book - should be observed during winter operation. Hydraulic oil • If the machine is not used for longer
periods at temperatures around and below freezing, warm up the engine by running at medium revs for approx. 3-5 min.
Engine oil • The oil viscosity (SAE class) should be
selected according to the ambient temperature at the machine’s place of operation.
• See lubricant specifications, section 3.9.2 Coolant • Before the beginning of the cold season,
check the level of antifreeze and adjust in line with the ambient temperature if necessary.
• At the factory, the antifreeze protection is set to approx. -25°C.
Battery charge • A good cold start performance requires a
well-charged battery. By warming the battery to approx. +20° (remove the battery after the engine has been turned off and store it in a warm room), the minimum starting temperatures can be lowered by 4-5°C.
• When installing the battery, ensure good contact of terminal connections.
• Only tighten terminal screws so that they are “hand-tight”, to prevent deformation of the terminal cones!
Fuel • Use only winter diesel fuel in winter, in
order to prevent cables becoming blocked through paraffin deposits. At very low temperatures, troublesome deposits may also occur when winter diesel is used.

• Seal off the air intake opening of the air filter system and the exhaust pipe opening.
• Protect tyres from direct sunlight. 7.8.2 During shutdown
• When the machine is out of use for 6
months, after this time all assemblies must be brought to operating temperature and manoeuvred for approx. 15 minutes.
• Beforehand, the anti-corrosion coat must be removed from the piston rods, and the openings of the air filter system and the exhaust pipe freed.
• After the manoeuvring cycle, preserve the machine once more as previously described.
7.8.3 After shutdown Before putting the machine into operation once more, the following measures must be carried out: • Anti-corrosion coat must be cleaned from
the piston rods. • The openings of the air filter and exhaust
pipe must be freed. • Clean the machine with a neutral detergent. • Check and install the battery. • Carry out all measures for putting the diesel
engine back into operation stated in the engine operating instructions.
• If the machine has been out of use for more than 6 months, the oil in the axles, etc. must be changed.
• Lubricate the machine according to the lubrication plan.
